Cano, 32, broke the little toe on his right foot when he was hit by a pitch in an exhibition game against Samurai Japan on Nov. 15. He was held out of baseball activities for about a month while the foot healed, but he is now fully recovered.
The six-time American League All-Star second baseman hasn't played in the Dominican League since 2008-09, but he asked Mariners general manager Jack Zduriencik this week if it would be OK to take part in a few games in his homeland this winter.
"Robinson approached us about playing games in the Dominican Winter League and we have granted him permission to play in a limited amount of games," Zduriencik said. "Robinson has reported to us his broken right pinkie toe is fully healed and he wants to get on a baseball field to test it before reporting for Spring Training. We look forward to Robinson reporting to Peoria, Ariz., in a little over a month ready to go for the 2015 season."
Cano is entering the second season of a 10-year, $240 million deal with Seattle. He's scheduled to report to the Mariners' camp on Feb. 24 with the rest of the club's position players, and the first full-squad workout is slated for Feb. 25.
Mariners pitchers and catchers are due to report on Feb. 20 and be on the field for the first time on Feb. 21.
